  "message": "vfs: call rcu_barrier after -\u003ekill_sb()\n\nIn commit fa0d7e3de6d6 (\"fs: icache RCU free inodes\"), we use rcu free\ninode instead of freeing the inode directly.  It causes a crash when we\nrmmod immediately after we umount the volume[1].\n\nSo we need to call rcu_barrier after we kill_sb so that the inode is\nfreed before we do rmmod.  The idea is inspired by Aneesh Kumar.\nrcu_barrier will wait for all callbacks to end before preceding.  The\noriginal patch was done by Tao Ma, but synchronize_rcu() is not enough\nhere.\n\n1. http://marc.info/?l\u003dlinux-fsdevel\u0026m\u003d129680863330185\u0026w\u003d2\n\nTested-by: Tao Ma \u003cboyu.mt@taobao.com\u003e\nSigned-off-by: Boaz Harrosh \u003cbharrosh@panasas.com\u003e\nCc: Nick Piggin \u003cnpiggin@kernel.dk\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Chris Mason \u003cchris.mason@oracle.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
